Due to higher price, limited supply and negative impacts on environment by fossil fuel,
automobile industries have directed their concentrations in reducing the fuel consumption of …

Aerodynamic drag reduction is considered to be one of the most effective ways to minimize
fuel consumption. Hence, this work focuses on reviewing some of the most promising …

Proper underhood airflow management of road vehicles has two distinct objectives, viz.
ensure the required cooling performance of the heat exchangers, and minimize the cooling …

Frictional drag reduction (DR) can lead to substantial fuel savings in marine vehicle
propulsion. The application of polymer coatings on vehicle surfaces has been found to assist …

Numerical investigations are carried out to investigate the reduction in the aerodynamic drag
of a vehicle by employing a dimpled non-smooth surface. The computational scheme was …

In this paper, a simple passive device is proposed for drag reduction on the 35° Ahmed
body. The device is a simple rectangular flap installed at the slant surface of the model to …

In the present world, passive control finds application in various areas like flow over blunt
projectiles, missiles, supersonic parallel diffusers (for cruise correction), the engine of jets …

The standard Ahmed body (SAB) represents generic road vehicles and is documented to
produce highly three-dimensional flow, which consequently affects the aerodynamic …

Road vehicles drag is a direct consequence of a large wake area generated behind. This
area is created owing to the vehicle shape, which is determined by the class, functional and …

This paper addresses the critical role of drag reduction technology in the evolution of road
vehicle design amidst the ongoing climate crisis. With transportation accounting for a …
